Let me share somethings with you all

1. DO NOT buy air purifier from Amway, Gintell, Ogawa. They are not professional HVAC maker but direct/retail seller, they OEM from china and sell high price under their brand. 4K for a purifier? The price just rip me off, that's how AMWAY send their "diamonds" to oversea trip every year. A good air purifier just cost around 500-700, I recommend Acson, AAF and Sharp. Easy to get from major electronics shops and easy to get filter replacement.

Putraskyline,

            12ftx8ft is not big, the air purifier should serve you well.
mleong,

            Why don't you enlighten us? I do not know Amway makes air purifier.

My home is nearby to cement machinery and every time the machine start to process the cement, the wind will blow to my home along with the filty dust...

Is it by getting more Air Purifier the only option I have in order to overcome this problem???

Thanks

mleong,
 
I am not buying all your crap here. Why you are avoiding your own statement? If you can give all of us here with satisfactory answer, not only I will buy a unit of Amway purifier from you, I will join Amway as your downline. How about that, dare to take up the challenge?

First you said I do not know what is behind the technology involved in the Amway Air purifier, I assume you know more than me. Let see..

1) What kind of tests that the Amway put thru the purifier?
2) What is the high tech behind the Fan motor design?
3) What is the total electricity operation costs (how much it costs you to run the device for a period of 1 month)?
4) We all know what the filters are all about, Acson, AAF and Sharp all use the same filters, you have to show us what is so special about Amway's pre filter, the HEPA filter and the Carbon filter that make Amway charge us 3k more despite lack of Plasma-Ionizer?
5) What is CADR rating? How does it affect the quality of the product?

Don't come back with "Too long to put it in words, come try my product, no obligation" crap.

arthurlwf ,

I will suggest you to install air-cond and air purifier for the sake of your family health. Buy baisc air-cond (without fancy features like purifier, ionizer, oxigen pump), if you use air-cond for long hours and can afford a little bit more, get a basic Inverter type and any of the air-purifier recommended above except "AMWAY PURIFIER". If you really are going for Inverter type, get a Daikin or Panasonic DC inverter.

dude, the guy does have a valid question and since you're promoting Amway's air purifier it's your job to clarify those question.
If you don't than you can't ppl to have doubt on you or the product you're selling:
To me, he seems to know better in regards to Air Purifier product than you do.
And like he mentioned and obviously to consumers, if the product is using the same tech and does the same job; why opt for a more expensive one?
So unless you can clarify why Air Purifier products from AmWay is more expensive I guess your recommendation wouldn't help here.
